Abstract

We demonstrate a novel photonic integrated circuit(PIC) that combines an ultra compact trench beam splitter with monolithically integrated photodetectors and modulators. A coherent receiver is realized by flip chip bonding of this PIC with an electronic integrated circuit (EIC). Preliminary system results yield a third-order intermodulation distortion suppression of 46 dB at a signal frequency of 300 MHz.
